I've been looking for a mug that had my rating patch, and this is the closest one I have found. There is a slight problem with one of the arrows. Three arrows should be pointing into the atom and one arrow pointing out and that one should be an outline. (See the picture of a correct rating patch I uploaded and the png drawing.). I believe you took the one listed on Wikipedia and that one is incorrect.
I can say the coffee stays hot.
Much better quality than expected. Keeps coffee hot. Nice clean lines on artwork. Feel free to crop pictures. Thank you
